It's a really cool idea, but I couldn't help but think they should move the water stop sign to well BEFORE the million dollar damage point I thought the stop sign was only visible because of the dark background (i.e. moderately lit tunnel) behind it? My first thought was similar - it needs to be seen sooner - but I presume that even some braking before slamming into concrete is better than none.

You mean, before the 3 flashing stop signs BEFORE he got to that point? A better idea might be a low bar that causes the truck damage well before they reach the tunnel. Only issue is how to make it safe and very obvious it's done the truck damage?

  The problem with a barrier that is hit is that you need to make sure it is structurally sound before you allow any other traffic past it. And if it leaves debris on the road, that needs to be cleaned up too. It's already a slow process to back out the oversized truck, so you don't want countermeasures that make it even slower.

    I wonder if a clearly labeled "all trucks go into this lane" well before the tunnel would work. You could have your barrier there, and not impede the rest of the traffic. You could even divert trucks into the car lanes while you clean up. One one hand, they're already ignoring signs. On the other hand, a sign that says "ALL TRUCKS go this way" might get a better, or at least different, response from "YOU are too tall".

  Depending on the truck, load, and barrier, that could be a hazard to other vehicles and occupants. Likely less so than the tunnel itself.

  Many places in Europe have a bar with chains, the chains hang off the bar at the height of the upcoming tunnel / bridge. Does of course assume that the driver will hear the chains knocking about on his truck...

  The whole point of the water sign is not to cause damage/kill regular cars that might be next to or in front of the truck.

The video shows why the stop-signs may be ineffective: https://www.youtube.com/watch?feature=player_embedded&v=NoTMC-uxJoo#t=0m45s https://www.youtube.com/watch?feature=player_embedded&v=... They use the blinking not only for critical messages ("STOP") but also for unimportant stuff ("slow down"). The boy who cried wolf...

I think they actually shut down the lights in the tunnel before the screen goes off. You can see it in the video when the lights go off and tunnel is suddenly much darker.

  Probably not the whole tunnel, just the entrance to enhance the projection effect. Remember there is still traffic in the remainder of the tunnel.
